LOW IN STIMULANTS

LONG LASTING ENERGY*

INCREASE PUMP AND STAMINA*

SizeSlim PRE-WORKOUT is designed to increase your energy and performance levels in the gym.*

SizeSlim PRE-WORKOUT provides you with the focus you need to help you get “in-the-zone” and power through your workout without the uncomfortable jitters.*

SizeSlim PRE-WORKOUT features key ingredients to help improve blood flow and provide you with a better “pump” while training. SizeSlim PRE-WORKOUT kicks in fast to increase stamina during exercise and stays with you until your last rep!*

3g
Citrulline Malate 2:1

This amino acid works to improve blood flow and nutrient delivery to the muscle cells during training, enhance nitric oxide production for better pumps, and helps to delay the onset of fatigue during intense training.*

1g
Beta-Alanine

Helps to increase training volume and strength by buffering lactic acid and thus delaying the onset of muscle fatigue.*

1g
Schisandra

This Chinese herb helps fight free radical damage and supports a healthy inflammation response due to exercise.* Schisandra has also been shown to support a healthy hormonal balance in the body, improving our ability to deal with physical and psychological stressors.*

750
Agmatine Sulfate

Works with Citrulline Malate to improve vasodilation which helps to improve muscle pumps. Anecdotal evidence suggests these pumps may help to increase the rate of protein synthesis, allowing for a potential increase in the rate of muscle growth.*

100mg
Norvaline

When your body produces nitric oxide it also produces enzymes that restrict that production. Norvaline works to inhibit Arginase which is produced by the body to inhibit Nitric Oxide production resulting in even better “pumps” and nutrient transportation during and after exercise.*

100mg
Choline Bitartrate

A neurotransmitter found to help improve mental function and energy. Choline Bitartrate as also been shown to aid in the improvement of overall brain health and mental focus by supporting the health of neurons and other brain cells.*

Flavor without sacrifice

clean. simple. delicious.

SizeSlim PRE-WORKOUT is sweetened naturally with STEVIA and is made with only NATURAL FLAVORS to support your healthy lifestyle without sacrificing taste or performance.

I got good energy and endurance with this product, but the taste was a little rough; I had to play around with how much water to add to make it tolerable. Perhaps bumping up the flavor a little would help. Really appreciate the all-natural ingredients and the inclusion of Beta Alanine, Citrulline Malate and a few others which I had never heard of but have interesting profiles, especially those promoting NO production. I would prefer a little more caffeine since I am stim tolerant but overall, a decent pre-workout.

im rather sensitive to stims so i was really happy to see that the caffeine was kept within moderate level in SizeSlim PRE. the pumps and focus are very good and longlasting. the Kiwi Strawberry flavor is nicely done and totally natural favored and sweetened. i though this was well balanced and effective!

Solid pre- workout. Provided a good amount of energy on some training days where I was training on little to no sleep. Energy lasted well after my training was over which is always a plus. Downside to this Size Slim pre workout is the taste and mixability. Taste wasn't that good, but it's not everything when your looking for a pre-workout.

i got a sample of the Kiwi Strawberry and while i am a stim lover i thought this was decent. while the formulation is transparent (which is commendable), its also a bit underdosed for my preferences. at almost 40.00 for 30 servings its also rather pricey. good but not great

for a low stim Pre, i thought this was an interesting product. the Kiwi Strawberry flavor kind of grows on you as you drink it. the energy, pumps and focus were all moderate to good. i especially liked the fact that everything is natural and there arent any artificial flavorings or ingredients. combine this with a totally transparent formulation and youve got makings of a product and company you can trust.
